To all whom it may concern;

Be it known that I, FnaivoisM. Barron, a citizen of the United States, and a resident of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in hfietalliclieea :torcements for Concrete Structures; of \vhichthe following is a fullyolear, and ex: act description. p

The invention relates to metallic'reentorcement for concrete structures. The object of the invention is to provide improved devices for securing crossed rods 01" reentorcement together.

It has heretofore been proposed to use continuous strips for holding crossed rods. such, torexample, as are used in helicoidal column-reentorcement, in properly spaced relation. In practice, it has been found that theme oit'long bars tor this purpose is objectionable, because of the ditliculty in simultaneously placing {111C securing a large number 0t crossing rods 1n position.

One object of the invention is to provide an improved reentorcement for securing crossed rods or bars together in which the securing-means comprises a series otclips which may be serially placed in position and which besides being provided with means for holding crossed rods together is provided with means for positioning and spacing the holding devices so that when these devices are serially secured along one rod, an entire series of crossing rods will be locked in properly spaced relation.

' The invention consists in the several novel features hereinafter set forth and more par ticularly defined by claims at "the conclusion hereof.

In the drawings: 1 is aside elevation of a floor reentorcemeut embodying the invention. Fig. 2 is aplan. Fig. 3 is a section taken on line oi 1. Fig. 3 is a section taken on line 3 3 of Fig. 1.v Fig. 3" is a section taken. on line 3 3 of Fig. 1. Fig. -11 is perspective of one of the clips for securing cross-rods together. Fig. 5 is'a perspect-iveot a clipwhich is adapted to hold two crossing rods. Fig.6 is a perspective of a reentorcement e1nbodying'the invention. Fig. is a perspective of a column reentorcement enibodying the invention. Fig. 8 is a detail perspective'ot' a portionotthereentorcement shown in Fig. '4'. Fig. 9 is a perspective of a modified form of the invention.

In Figs. 1 to 6, the invention is exemplitied in a floor reenforcement comprising crossed rods 10 and 11 and a series clips 12 of round wire for securing the crossed rods together and in properly spaced rela- ,tion. Each clip 12 comprises a hook 18 at one end adapted to extend under the rod (Z, a portion 1 1 adapted to extend longitudinally of said rod, a loop 15 adapted to receive one of the crossing rods 11 to space and hold it at the desired point on rod 10, and loops forming upstanding tongues or projections 16 and 17 which are connected by loop 18. Each clip 12 is provided between its hook 113 and its loop 15,3vith laterally extending opposed loops 19 and 20 which are adapted to pass around and between the tongues 16 and 17 of the nextclip and thustorm a longitudinal and lateral interlock between the adjacent ends of the clips. These loops 19 and 20 are also adaptedto overlie and engage portions of the ad aCent cllp and thus lock the latter down against the rod 10. The loop-18 of each clip is extended downward to form a leg adapted 'to rest on temporary staging 21 and the lower end of each loop 171s also" while the hook is tilted, so that the hook will be substantially at right angles to said rod. The crossing rod 11 to be held by the clip is placed into position to enter the loop 15 and then the clip is swung downwardly .to bring the longitudinal portion 1&1 againstor alo. side of the rod 10. Thiswill bring the lowerend oi loops 1'? and 18 into position to support the reenforcement and'loops 16 and 17 will be in position to be locked to the rod 10 by the next clip. The next clip is thenconnected to the rodlO'in like manner, its book being slipped under the together in properly spaced relation rod 10 while the clip is in tilted position. \Vhen the latter clip is swung dinvnn'ardly to bring; its longitudinal portion is; along; side of the rod 10, the loops it and It? will pass between the lateral loops i9 and 20 ot the second clip and will p ;s around the loops to and'l? of, and. will overlie, theiirst clip so that the hook end oi thes-condclip will lock the adjacent end of the first clip against separation from the rod lO and will also be interlocked against relative longitudinal movement and lateral movement. As many clips as desired may be'serially applied to the rod 10.

This construction exemplifies a reentorce ment in which the crossedrods are y 1? which are interlocked to rel 'ively space or another and which are provided with meai to hold and space the crossing rods. The construction also exemplifies such a reenforcement in which each clip is adapted,

with a hook at one end to engage the r d and with means at its other end which adapted to be locked to the rod by the hook of the next adjacent clip. An ll iportant l- *antage of this construction is that the ore ing rods and clips may be successively applied to the longitudinal rodv and in this manner the work of aesemhlins: the reen- Forcement is greatly exped t d.

In Fig. 5, the clip 12 similar in construction to the clips herein nore described: except that it is provided with plurality of loops 15? so that each clipwill ser 4 to hold andspace a plurality of crossing rods 11 In Figs. 7 and 8, the invention is illustrated as applied to a column-reent'orcement comprisinga series of helicoidal members ll and longitudinal rods 10?. The clips are similar-in construction to those hereinbetore described, except that in some instances the loops 15 are adapted to receive the lapped ends 11 member. I

In the constructionshown in Fig, 9. a plate 25 is adapted to be slipped over the en d of the rod 10 to lock the clip 12 at the end of the series of clips or adjacent the end or the rod 10 to said rod r The i vention is" not to he unde -s restri ed to thedet I r I may be modified with pe of the appended claims, without from the spirit and scope of the inven on.
